Because of heavy armoring throughout, and most likely a host of top-secret protection and counter-assault equipment, these cars are as heavy as a tank and get less than 5 mpg.

The new one is likely to ride on a medium or heavy truck platform produced by General Motors. By some estimates, it will be fitted to the same chassis found on some Chevrolet or GMC haulers – the kinds of vehicles you would typically see as large moving trucks, for example.

Its bodywork features a combination of various heavy materials, including steel, aluminum, titanium, and ceramic.
